To cZZ whom it may concern Be it known that I, WILLIAM E. Moose,

a citizen; of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements inCotton Grinning and Cleaning, of which the following is a specification.

This invention relates to the ginning and n cleaning of cotton or other fibrous material,

and the principal objects of the said invention are; first, to improve the ginning proper by providing for the doflingof the gin saws by air in Such manner as to increase the cleanliness of the cotton and to diminislrthe energy usually necessary in air-dofiing gins; and, second, to provide improved means for the cleaning of the cotton between the time that it leaves the gin and the time that it reaches the condenser.

Other objects of the said invention will more fully appsr from the following description inwhich reference willbe had to the accompanying drawings forming a part of this specification and wherein,

. Figure 1, represents in top plan and partly in section combined ginning and cleaning apparatus embodying my said invention; Fig. 2, a vertical fragmentary sec: tional View of a gin constructed according to my invention; Fig. 3, an enlarged detail fragmentary perspective view showing the constricted gin saw'doiling air passages; Fig. 4, an enlarged fragmentary section taken on ight; Fig. 5, a cross-section of the cleaner taken on line 5-5 Fig. 6 looking to the right, and Fig. 6, a vertical longitudinal section of said cleaner taken on line 66 Fig. 5 looking to the right.

Referring first to the construction of my improved gin proper, this comprises, among other parts, a roll box 1 of any suitable construction in which are mounted the gin saws 2 and ribs which also may be of the usual or any suitable construction. g i

For the purpose of clofiing the lint cotton from the saws,l provide an air dofiing arrangement of peculiar construction. This consists, in the case shown, of an'air inlet line 4: having its mouth 5 opening through the gin frame to the outside air and having a constricted throat 6 provided with a series of slots 7 through which extend the gin saws to the interior of the throat. The throat 6' is gradually constricted from its upper port ammate of new na e. PatentedApr. 2?, 12535 A lication ins; he: 16, 1am,- femai No. 427,413.

ticn to the. doffing points when gradually gets larger and merges into an outlet fine' Q of greatly increased area over'the restri'c'tiid threat, the latter fiue passing throughthe gin frame to the outside B nieans of this,

construction l produce a entnri-tube-ef feet, which produces an 'efitznmelyhigh velocity of air at the doting point with a comparatively small'ekpenditnre of power. The velocity of the air at thedofiing point may be increased by further constricting thepassage of air in the threat, 6 at the being spaced fan enough apart to permit of free rotation of the saws. The large air passage; l tapering-to a passage or throat of greatly decreased area at the 'dofimg point, then expanding into a passage of relatively greatly. increased. area produces the maximum doliing eliect with the minimum expenditure of power at theexhauster and also allows the gin to mote properly;

In practice the gin saws pull'through the gin ribs a considerable amount of trash and dirt "which would naturally have a tendency to pass through the slots 7 andthen'ce into the exhaust tube 9, mixing With.the cotton therein. In order to avoid this, the gin is provided with a chamber 11 extend ingtransversely across the gin and having air inlet passage 12 between the to wall 13 thereof and the top'of the flue 4-. necting this chamber to an exhaust fan as through an opening 14, a suction ma be created in the chamber 11 which will raw into said chamber through passage 12 most- .of the dirt which is drawnthrough theribs.

by the saws: In Fig. I, 15 represents such an exhaust inn connected to the chambers 11,-11 of the t 'sggins 16 and 171 through ducts 18 and 19. g l

20 is inenelyan outlet from the fan 15 for the air and dirt from ducts 18 and 19.

Fig. 1' also shows. these gins connected let 2.1 and 22 represent exhaust fines leadingl' from the exhaust doffing lines 9. (if-the re} 19 spective gins to an inletpipe 23 of acotton cleaning device 24;. This latter devicewmentire length of the said drum. This cy lindrical screen has an inlet opening 27 registerin with aninlet pi e 23, 18 closed at one en 28bythe head the casing and opens at its other end into the chamber of an exhauster 29-in the casing oi which is mounted a fan 30 on a shaft 31 which extends axially'through the cylindrical screen 26, being mounted at its ends in suitable bearings, Mounted fast on tlns shaift within the screen '26 are a plurality of spiders 32 'nich carry bars 33 adapted to be rotated by said shaft in close proximity to the inner wall of'the screen 26. Rotary motion may he imparted to shaft 31 through pulley 34 from any desired source. The screen 26 being in the form of a complete cyllnder, the cotton is given one or more revolutions in a spiral path as itoes longitudinally through said screen. he bottom of the casing 25 forms a hopper 35 provided at its bottom with an outlet 36.

The exhauster outlet v37 4 is connected through any suitable duct 38 with a condenser 39 of any desired construction.

In practice the fan of the exhauster 29 is rotated so as to create an air current passing into the gins. at the inlet flue t, thence past the gin saws, through fiues 21- and 22, to the cleaner, to the fan of the exhauster .29, from .which part onward to the condenser the air becomes a forced blast in contradistinction to an exhaust. By means of this air current the cotton is first dolled from the gin saws, then transported to the cleaner where it passes into the screen 26. Here it is beaten by the rotary bars 33, the dirt passing downward through the screen to the outlet 36; The cotton is themsucked through longitudinally of the screen 26 into the cxhauster 29 'Where it-is then forced along to the condenser. Under ordinary circumstances the single fan 30 unless very large and rotated at an extraordinary speed would not be sufficient to do .all this work, hutowing to the arrangement of the air fines at the dofling points, herein described,

the necessary power to efi'ect the doiiing is greatly reduced. This arrangement also makes it possible to make the lint fines from the gins to the cleaner and from the v cleaner to the condenser much smaller therefore at a lower cost. Morcovcr, as the exhauster 1S much more positive in its operat on than the an currents induced by-the :ordinary gin brush cylinder, there is a de- 'cidcdly less tendency in spy-apparatus for the lint fines-to choke. my invention also makes it possible to use-a much smaller condenser with loss screen area than; is ordinarily used. Furthermore, my improved method of airhandling the exclusion fromthe lint cotton of dust and dirt from the gin saws, the thorough cleaning to which the lint is subjected bet'ween the gin and the condenser, all greatly improve the 79 quality of the cotton sta ,an air dofiing flue having a constricted .throat provided with aseries of slots into which extend the respective 'n' saws. 86
